PoLlsHlNG-MAQHINE.

SPECIFICATION forming part of Letters Patent No. 615,383, dated. December 6, 1 898.

Application filed March Z2, 1898.

To all whom t muy concern.'

Be it known that l, FERRAND F. ELLIS, of Oneida, in the county of Madison, in the State of New York, have invented new and useful Improvements in Polisliing-lllachines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Myinvention relates to polishing-machines.

My object is to produce an improved machine in which the work-holders are sectional and mounted upon therim of a revolving wheel, the work-gripping jaws and form being mounted thereon to be automatically rocked longitudinally upon the upper or reciprocating section of said holder, which is adapted to be automatically oscillated laterally and to automatically yield and return vertically and to automatically drop out of the path of the polishers and to be automat'- ically returned thereinto, in`wl1ich the polisher-shafts are arranged upon lines radial to the circle of the work-holder wheel and are adapted to be automatically reciprocated in their bearings simultaneously with the rocking, oscillation, and vertical reciprocation of the work and work-holding grips.

It also embodies other features of construction and operation and combination of elements to carry out its purposes and accomplish the desired results.

It is constructed as follows, reference being had to the accompanying drawings,in which- Figure 1 is a front elevation. Fig. 2 is a vertical section of Fig. 1 on line a; a; in Fig. 3. Fig. 3 is a top plan. Fig. t is a section on line y y, Fig. l, showing some ot' the central portions broken away to expose others to view. Fig. 5 is an enlarged elevation of one of the holding and polishing mechanisms, of which six are shown in Fig. 3, the parts being in their operative positions. Fig. 6 is a vertical section-thereof, showing the brush moved to the left andthe work-holder tilted in the same direction an'd passing under the brush, as in polishing the right-hand side of la convex surr'rinent with the brush, as when holding no Serial No. 674,809. (No model.)

work, the dotted lines indicating its normal 5o position. Fig. 8 isa plan of the cam for oscillating the work-holder. Fig. 9 is a plan of the guide-plate to guide the reciprocation of the cam-actuated arms. Fig. l0 is a vertical section of a work-holder, showing the jaws in position to' hold work. Fig. 11 is a like view of the same, showing them closed. Fig. l2 is an elevation of a work-holder holding a piece of work and about to engage with a polisher. Fig. 13 is a sectional view of the same, showing the work passing through under the pol isher. Fig. 14 is a top plan of Fig. 12. Fig. 15 is a like view of Fig. 13. Fig. 16 is a sectional view of a polisher and a work-holder passing through, under, and out of contact with it, there being no work in the jaws. Fig.

17I is a top plan of the same, the polisher being partly broken away.

A is a suitable base, upon which a spindle or post 2 is rigidly erected, and 3 is a sleeve loose 'upon said spindle. Upon this a drivegear t is secured and driven by theworm and shaft 5 or in any other suitablemanner to drive the main gear 6, also secured upon said sleeve and partly supported, steadied, and guided by a track 7 and a flange 8 on said gear or by other suitable means, which is rather essential, as this gear is quite large. At suitable points on said bed standards 9 are erected, in which drive-shafts 10 are suitably-journaled to be driven by pinions 11,and by means of the pulleys 12 13 and belt 14: to drive the polishing-shafts l5, journaled upon said standards, and thebrushes or polishers 16 thereon. Each brush-shaft is adapted to be reciprocated by means of a clutch member 17, a lever 18, engaging therewith, and a cam 19 upon and driven by the shaft 10. These several driving-shafts lO and polishing-shafts are mounted upon lines radial to said main gear. Around said` sleeve a stationary cam 20 is suitably mounted, as upon posts 2l, as shown, and provided with recesses or cavities 22 at spaced intervals, and 23 is a roller or other traveler suitably engaging with said cam and following its contour. This roller is slot and pin 26, and to this bar the workholder is hinged, as at. 27. Said ways and pins are suitably mounted upon `the rim of the work-wheel 2S, mounted upon and driven by said sleeve. This work-holder, Figs. 12, 13, and 16, comprises a bifurcated body having ways in which a block 29 is suitably mounted to be reciprocated, being in its normal elevated position, by the rods and springs 30, a suitable pin 31 regulating its upward projection. Upon said block a work grip is suitably hinged, as at 32, comprising a body 33, a form 34 thereon, a stationary jaw 35, and a movable pivoted jaw 36, having an arm 37. A spring 38 at one end and a pin 39 normally hold said grip in a horizontal position, or two springs, one at each end, can be used, whereby said grip can be tilted longitudinally, as shown in Fig. 3. The hinge-joint also permits the upper part of the holder to be rocked to swing the grip laterally. Both said tilting and rocking are performed automatically.

Vhen a piece of work, as a spoon 40, is gripped upon the form which is complementary to it, the tilting is effected by the pressure of the polishing-brush, and the brush is thereby enabled to enter the concavity of the back of the spoon bet-Ween the handle and the bowl. (A spoon is here spoken of simply as an article of irregular contour and to illustrate the adaptation of the machine to work upon irregular surfaces.)

The grip is swung laterally by the following mechanism, Figs. 1, 2, 5, 6, and 7: Upon the post 2 a cam 41,-Figs. 6, 7, and 8, is suitably secured, its cam-lip 42 engaging with a reciprocating pitman a, which is connected by alink 43 to the block which carries the grip. The pitman is seated in a radial groove 44 in a revolving guide 45, Fig. 9, secured upon said sleeve, and said work-wheel, workholders, pitman-guides, and grip-pitman revolve together, while at the same time" said pitman is reciprocated by said cam and said grip oscillated. Thus when several polishers are employed the grip will present the Work in a horizontal plane to the rst one at an angle in one direction to the next, as in Fig. 6, and so on, giving a different presentation to each one, while at the same time the work will yield vertically and be tilted longitudinally, all while making one revolution of the work-wheel, and whereby all parts of an irregular shape will be polished uniformly.

In Figs. 6, 10, and 14 the grip-jaws are shown open, as when gripping an article, and in Figs. 7, 11, and 17 as closed or/empty.

The movable4 jaw 36', Figs. 5, 6, 7, 10, and 11, is provided with a leg 46, which normally engages with the upper end or head of the rocker-lever 47, which is pivoted upon the work-holder body just below the hinge 27, substantially as shown in Fig. 10, in which the jaw-spring 48 is quiescent, enabling the lever-sprin g 49 to throw the bolt 50 to the left into the opening 51 in the vertically-movable part of the work-holder body, and thus supl port it and the grip in their normal positions to bring the' work into engagement with the polishers. When the work is inserted between the jaws, the foot of this leg is thrown and held away from the lever-head, thus enabling the lever-spring to act upon the bolt, and when the jaws are empty, as in Fig. 11, the jaw-spring in closing the jaws tilts the lever to withdraw the bolt and permit the movable part of the work-holder to drop out of or below the path of the polisher, particularly when the roller 23 enters a recess 22 in the cam 20, and at the same time the pitman can be so timed as to tilt the grip, as shown in Fig. 7. This protects the jaws from the action of the polishers. Then as said roller leaves said recess said work-holder is raised bodily to such a height that the pin or pin and roller 52 will suitably engage with the upper side of the stud or stud and roller 53, which will lift the movable part of the workholder into position to permit the bolt to reenter said opening and again support this part in its operative position.

Uponl the upright 2 an arm 54 is secured, common to all of the work-holders, and provided with a wedging or cam head 55, (best shown in Fig. 3,) with which the arm 37 of each movable jaw will engage to open the grip-jaws for the insertion of work and release it to close upon and grip the work, or to wholly close against the stationary jaw. The work is usually inserted and removed while the jaws are thus automatically open, so that the revolution of work-holders is continuous.

In Figs. 1, 2, and 3 a sleeve 55 is adapted to be reciprocated by the lever 56, links 57, and springs 58 to raise and lower the arms 59 and holders 60, in which the polishing medium, as rouge, is held to supply the polishers therewith whenever desired.

I have heretofore described the gear 6 as secured upon the sleeve 3 and driven by the gear 4 and worm-shaft 5; but 1 have also shown in Figs. 1, 2, 3, and 4 a separate driving mechanism for the gear 6, which is therein loose upon the sleeve, comprising a bevelgear 6l, driven by a shaft 62, and power suitably applied to the pulley 63. In this construction the worm, through the gear 4,drives the work-wheel, work-holders, and pitman and cam and guides, and I am enabled to drive them at a different speed from that of the polishing mechanism, which is usually desirable.

It will be seen that the dierent movements of the work-holder and grip enable lne to readily polish objects of irregular form.

It will be seen that the grip block or form shown in the drawings is complementary t0 a spoon; but it will be evident that this can be changed to be complementary to any irregular shape 0r can be plain, in which case IOC IIO

the longitudinal tilting of the form can beV 4without departing from the spirit of my invention.
